What gps? Be careful as I tried to do this with my hema hn5 and cut the cord only to find out the ciggie plug actually houses a voltage/amp altering circuit board and it won't work with out the plug or some more extensive modifications to it all. I just rejoined the wires and went back to the plug. Haha. I now have a new cable (many years later)

Yeah good point probably worth checking the plug with a multimeter
